Materials Data on InBr2 by Materials Project
InBr2 crystallizes in the orthorhombic Pnna space group. The structure is three-dimensional. there are two inequivalent In2+ sites. In the first In2+ site, In2+ is bonded in a tetrahedral geometry to four Br1- atoms. There are two shorter (2.55 Å) and two longer (2.56 Å) In–Br bond lengths. In the second In2+ site, In2+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of In–Br bond distances ranging from 3.48–3.57 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to three In2+ atoms. In the second Br1- site, Br1- is bonded in a single-bond geometry to three In2+ atoms.
